How do I style my code blocks in a Marp presentation?

Question

I want to up the font of a code block on one of my Marp slides.

How can I style an individual code block without also effecting surrounding text?

Answer 1

Turns out that marp respects scoped on style tags, apply the style only to the current slide.

The code blocks are likely the only item on the slide using a pre tag. Thus

---
# I am slide

<style scoped>
pre {
   font-size: 2rem;
}
</style>

```cs
// I am code block
\```
